CQINflON'TROI-LLD APPARATUS FOR DISPENSING LIQUIDS.

Application filed iqovember T all whom it may concern:

Be it known that I, Mama);- L'. Bron, a citizen of the limited States of America, residing at Lansing. in" the county of Ingham and State of Michigan, have invented certain new and useful Improve ments in Coin-Controlled Apparatus for Dispensing Liquids, of which the following a specification, reference being hadfthcrein to the accompanying drawings.

This invention relates to coin controlled apparatus for dispensing. liquids and es pecially to means whereby we te is avoided, and whereby the parts may e readily inspected, cleaned and sterilized without throwing the machine out: of adjustment.

The invention consists in the matters here:

inat'ter set forth and more particularly pointed out in the appended claims.

In the drawing, Figure 1 is a view, partially in central, vertical section, and partially in elevation, of an apparatus embodying features of the invention; Fig. 2 is a view in detail of-a preferred form of coin controlled locking means. Fig. 3 is a view in longitudinal section of an automatic measurine faucet, or volumetric valve. Fig. 4: is view in cross-section of the valve through an outlet and vent pipe.

in its preferred form, an appropriately designed casing 1 of metal or other suitable material is divided by a horizontal partition or diaphrag in .2 into an upper chamber fOl'llllHfl an ice box, which may be closed by a lid {3. and a lower compartment housing measuring-mechanism.

.\ liquid receptacle or supply tank 5 of 1 glass or like suitable non-corrosive material which may bereadi ly cleaned and sterill ized, has a turmehshaped lower end 0 which extends through a central aperture in the l partition 2, leakage being prevented by a packing ring 7 of rubber or like suitable material which is held in place bya false 5 bottom 8 properly secured to the partition.

, The lower protrudilur margin of the packing is clamped around the tank by a clip 9. The upper end of the receptacle may haye a separate cover or may be closed by an elastic ring 1-1 secured by concentric flanges 12 on the casing lid 3. The tunnel stem 1. -3 is secured in an aperture in a crossbrace ll in the lower compartment and a nipple 15 is cemented or otherwise secured therein.

The inlet 1.6 of an automatic measuring faucet or volumetric dispensing valve, is atv 4 Specification of Letters Patent.

I tat-lied by a suitable coupling 17 to the'nip ple 15 of the tank. In its preferred form the valve consists of a tapered cylinder 18 i having an outlet 19 and an air vent 20 from g which a vent pipe 21. extends through the diaphragm 2 to a level with the upper end of the tank. A. rotatable hollow closure is held to seat in the cylinder by a spring cli or finger 23 snapped over the larger enc. It has an intake port 2 1 and vent aperture 25 which may be broughtsimultaneously into register with the inlet 16 and air vent 20, respectively. A discharge port 26 and second vent aperture 27 may likewise be broughtsimultaneously into coincidence with the outlet 19 and air vent 2t) respectively, by, a part turn of the closure. A removablysecured head closes the larger end of the latter and a stop pin 2!) in the cylinder engaging a marginal notch in the head or other preterredmeans defines the closure movement in a familiar manner. The capacity of the closure may be adjusted by a displacement plug 30 screw-- threaded through an aperture in the head 28. An axial stem 31 on the smaller closed end of the rotatable hollow closure has a notched end or is otherwise fitted to nonrotatively and detachably engage an alined spindle 32 journaled in a cap 33 in the. casing wall and turned by an outer handle which when depressed. swings the closure to discharge position and when returned by a properly disposed spring 35 and lever arm 36 closes the discharge and permits the valve I to fill.

A pipe 37 slu'iported in the wall of the casing. delivers the contents of the faucet at any desired point, as, for example, in a drinking glass placed on a bracket 38 on the rasing. The pipe is not directly attached to j the valve outlet 19 but has an expanded end or funnel 239 at, an interval below the 'alve whereby air enters and allows the pipe to draimso that no drops adhere to the mouth. A petcock 40 from the funnel connections for drawing oil the reservoir at will and a drain cock ll for the ice tank are also provided.

. Coin controlled mechanism of any suitable design locks the handle in its aised normal position. In its preferred form, a lever 42, whose outer deeply grooved end 43 is depressed when a coin is dropped there i in from an inclined coin-track 44 leading 1 from a slot-plate 15, has a detent pawl e6 which interlocks with the notch of a flange l? on the spindle 32 over which the lever is pivoted on a Stud 48 when the outer end is elevated by the combined action of an ejector arm it) on the flange and a counter balance 50 adjustably secured on the inner end of the lever. A ma netic trap formed by cutting away one site of the tracl-r. or chute near the slot plate and securing a magnet 51 .with its poles adjacent thetrach, whereby a slug of iron or the like is pulled from the track, a slot 52 in the coin receiving end of the lever which allows undersized coin to drop through unimpeded, and

proper disposition of the chute frictionaily, arrest rough or soft metal non-magnetic slugs as they pass the magnetic gap, complete the essential. features, stops 53 main "used to limit the movement of the lever an coin.

()ne feature of the apparatus is the accessibility of the parts, whereby they may be readily cleaned. The hollow valve closure may be quickly withdrawn from its cylinder and its head removedtor washing outthe interior without disturbing the displacement plug, the latter forming an additional fee ture by which the quantity of liquid to be discharged may he regulated to a nicety.

Another important feature is the venting of the valve, whereby the latter acts quickly and freely at all times and is always completely filled and emptied, thus preventing emptied, rushes out with suiiicient velocity" to sweep along any particles or drops which would otherwise adhere to the ,tuhe, thus leaving the tube clear at once instead of trickling out with diminishing force, and dropping slowly at the last.

Obviously changes may be made in the details of construction 'without departing from the spirit ofthe invention and I do not care to limit myself to any particular form or arrangement of parts.
